Wirth W, Eckstein F, Culvenor AG, et al. - This study was sought to correlate the five-year change in femorotibial cartilage thickness in 121 young, active adults with an acute anterior cruciate ligament (ACL) tear randomized to a strategy of structured rehabilitation plus early ACL reconstruction (ACLR) or structured rehabilitation plus optional delayed ACLR. Researchers randomized 62 patients to early ACLR, 59 to optional delayed ACLR. At two- and five-years follow-up, MRI was acquired within four weeks of injury. The findings revealed that the choice of the treatment strategy for the injured ACL did not modify the magnitude of five-year change in overall femorotibial cartilage thickness in young active adults with acute ACL-injury.
